The unit can also be set to beep on completion of the sample, and the flow alarm can be enabled,
which will cause an alarm condition if the flow deviates beyond
10% from nominal.
The sampling process can be initiated from the main screen by pressing [
START
]. After the
sample delay has expired, the bright green sample LED will light to provide a high visibility
indicator of sampling in progress. Sampling can be stopped at any time by pressing [
STOP
]
(unless the secure sample option has been enabled). Following completion of the specified
sample volume, the pump will shut off and the bright green sample LED will flash (until a
button is pressed) to provide a high visibility indication. If the unit had been powered up with
no labels in the printer, then the screen will display a message giving the date/time that the
sample ended. Otherwise, the number of labels specified in the setup menu will automatically be
printed, and a message will appear stating that label(s) are being printed. After the label printing
is completed, a new message will prompt the user to either print additional labels, advance the
printer to the top of the next label (to correct suspected label misalignment), or simply exit to the
main screen. Also, the beeper will sound six times at sample completion if that option had been
enabled in the setup menu.
2.2
Setup menu options
The setup menu is entered from the main screen by pressing [MORE] followed by [SET UP].
The screen after pressing [MORE] appears below. The setup menu has a variety of options that
can be set to control the sampling, label printing, alarms, and other features of the CI-90. To
ensure that these settings are retained, the user must press [EXIT] to return back to the main
screen before turning power off. Pressing [EXIT] causes these settings to be stored in non-
volatile memory. Thus, they are retained when power is off, the unit is unplugged, and even
when the battery is disconnected.
2.2.1 Sample volume
The CI-90A has a number of preset sample volumes from which the user can choose. The
minimum sample volume is 5 liters, which equates to a 3 second long sample time. The
maximum sample volume is 1100 liters, which is 1.1 cubic meters and takes 11 minutes to
complete. Sample volume choices available are 5,6,7,8,9,10,20, … to 1100 liters in 10 liter
increments. An additional sample volume of INF is available (primarily as a maintenance
feature) which runs the pump until the user presses [
STOP
].
To select a sample volume, the user must first enter the setup menu, if not already there, and
then use the up/down arrows as necessary to scroll the sample volume line to the top of the
screen (as shown above). Once there, the current sample volume choice will blink, and the user
